The surveyor at our dig in Tucson kept yelling at me to stop swinging the trowel, and he was right
I was scraping a wall trench at a site outside Tucson last Tuesday when I caught a flake of worked chert under the blade and nearly sent it flying into the screen, so I switched to a bamboo tool and a brush for the rest of the unit, and now I want to know if anyone else has a rule for when to put the trowel down for good.
